(CBS) — You don’t have to drop pennies in the proverbial piggy bank any more. Now, you can use apps and online banks to set up automatic savings.

CBS 2 Cost Cutter Dorothy Tucker shows you how.

Download Digit and start saving. Just connect it to your checking account.

Every day, Digit takes a few dollars and transfers it to a savings account. It pays a 1 percent bonus every year.

Another app – Acorns — uses your debit or credit card to save money.

“You purchase an item from, say, Starbucks for $5.50. It’ll round up to $6, take the cents and invest the difference,” says Larry Ludwig from Investor Junkie.

Stash away just 40 cents a day and in 10 years you could have nearly $4,000.

A third option: Chime. An online bank that rounds up purchase amounts and stashes the pennies in a savings account. You earn a 10 percent bonus on your weekly stash.

The savings can add up.

“Anywhere from a few hundred dollars to a few thousand dollars a year,” says Ludwig.

There are no fees for Chime.

Digit is free for the first 100 days but then $2.99 a month after that.

Acorns is $1 a month for accounts under $5,000 but free for college students for four years.
